OK Cecil, if the 2nd harmonic is 42% of the amplitude of the fundamental at the
plate of the tube, can you determine the amplitude of the 2nd harmonic at the
output of a pi-network having a Q of 12?


I think I understand ideal class-A operation pretty well.

What I am trying to understand is: In class-B operation,
if the frequency of interest is made up of less than 1/2
of the current through the amplifier tube, is more than
1/2 of the current not conjugately matched?
